No Spotify for you, DebianAfter tearing at my non-existing hair for a couple of days I've figured out that Spotify's new web interface uses html5 and DRM, and you need a browser that supports this to play it. Firefox seems to download something when you turn on DRM (preferences->Content->Play DRM content) and Chrome is compiled with proprietary codecs turned on. Chromium, and browsers using QtWebEngine that is based off of Chromium, does not support this.

The bright sideNow for the bright side, if you use Chromium or a browser like QupZilla using QtWebEngine you can snatch

from the Chrome installer and then put them in /usr/lib/chromium. This might also allow you to watch Netflix and similar sites in Chromium.

The ugly sideThe alternative is to get libssl1.0.0 from Jessie Backports and install the native Linux client but then you're using an old lib, and it might give weird bugs because you're not supposed to. An alternative is to get libcrypto.so.1.0.0 and libssl.so.1.0.0 from libssl1.0.0, put them in the same directory as spotify, remove libssl1.0.0 from /var/lib/dpkg/status, pin spotify-client, and start it with

EDIT: After doing a full upgrade the above issue seems to have disappeared in 1.0.49.125.g72ee7853 - still has to be launched from the terminal but that's not an issue.

Also, anyone reading this topic in the future may be interested to know that the Spotify web player appears to have been greatly improved and works without Flash. On the Spotify forums the devs were saying only three weeks ago they were rolling out an HTML5 version, and this seems to have been implemented.

Could you please edit your first post so that people immediately know you are coming across these problems on Testing and not Stable? A simple addition of "Testing" or "Stretch" in the title would be enough. Thank you.
